Explanation:

• there are many substances which have variable valency. The variable valency is due to the presence of the orbital which filled if  by more number of electrons than the valence shell.

• As a result of this there are plenty of ions or compounds that can be formed by a particular type of atom

• the non-existing compounds or ions are those which does not feel the alternative variable valency of the particular element
